To Z5 whom it may concern..-

Be it known that I, OTTMAR Mimonnrna Lnu, a citizen of the UnitedStates, residing at Baltimore, in the State of Maryland, have inventednew and useful Improvements in Machines for Producinglypc-l\Iatrices,Printing, &c., of whiehthe following is aspecification.

My invention relates to a machine for pro IO ducing impressions fromtype upon paper or other pliable or plastic surfaces, whereby astereotype mold may be obtained direct; and the novelty consists in theconstruction and arrangement of parts, as will be more fully hereinafterset forth, and specifically pointed out and indicated in the claims.

The object in general of the invention is to avoid the work ofthecompositor, and theheavy expense in type by means ofa mechanical mazochine, through the employment of which the molds or matrices areproduced direct in the machine without the aid of con'ipositors, andwithout any further stock of type than those contained in the machine.

2 The specific objects of the invention,among others, may be brieflysaid to be to produce a machine which shall be capable of having aseries of disk type-wheelsarranged in such relation to each other as topresent any given type in each disk at a pointwherc theimpression is tobe taken, the particular type in each case being determined by a seriesof keys, each bearing a design corresponding to one of the types on eachof the keys; to provide means 5 for automatically shifting thedesignating levers from one disk where the proper letter or figure hasbeen designated to the next disk in the series; to provide means forautomatically pressing the designated types together,

and locking them until the impression has been automatically taken, andthen releasing them for a subsequent operation; to produce means forautomatically causing the return of the designating apparatus after theimpres sion of certain types has been taken, in order that other typesmay be designated and arranged at the point where the impression istaken for a subsequent operation; to provide means for automaticallybringing the several types designated on the several disks into a line,and locking them until an automaticallyoperating platen shall havepressed the paper or other surface to the face of the designated types,and then automatically releasing t'he entire series.

To these ends the invention consists, essen tially, in the mechanismsand combinations of mechanisms fully illustrated in the accompanyingdrawings, which form a part of this specification, and in which Figuresland l on Sheets 1 and 2 represent a top plan view of the devicenecessarily broken in each sheet. Figs. 2 and 2 are longitudinalsections taken on the line as w of Figs. 1 and 1. Fig. 3 is a transversesection taken on the line 1 1 of Fig. 2. Fig. 4 is a detail sectionshowing the type disks,the shaft upon which they are loosely hung, andthe intervening spring-friction spiders. Fig. 5 is a detail view ofoneofthe type-disks showing the radial recesses therein which receive thetype. Fig. 6 is a detail showing the spring-friction spider having thespring arms projecting alternately and the key-projections for lookingit to the shaft. Fig. 7 is a detail perspective of one of the type-arms.Fig, 8 is adetail of the segmentand rack-bar and some of theirconnections. Fig. 9 is a detail perspective of the oscillating pawl.Fig. 10 is a detail of the connectinggear on the main shaft and its 8cfriction connection therewith. Fig. 11 is a detail perspective of themeans for compacting and locking the designated types. Figs.

12 and 13 are detail sections of the type-pins, their concentricbearings, and the elastic band which exerts a constant force to hold thepins out of operation, one of the pins being shown as locked in positionand in the act of designating one of the types.

Referring to the drawings, in which similar 0 letters of referenceindicate like parts in all the figures, A designates the drive-wheel,hung rigidly upon a sleeve, 1, which in turn is loosely hung upon ashaft, 13, journaled in proper standards, as shown. The wheel A 5 andits sleeve have belt or other connection with a suitable motor, andrevolve constantly when the device is in operation. The sleeve transmitmotion to the'main shaft D,journaled longitudinally in the frame X bymeans of a concmo-convcx friction-disk, 9, located between the body ofthe pinion 9 and the end of the main shaft D. On the opposite end of theshaft D is an arm, 10, and pivoted in thcmain frame X, just back of thekey-board, is a bellcrank, 11, operated by a key, 12. A keyspring, 13,serves withaconstantforce to hold the inner arm of the bellcrank lever11 against the arm of the main shaft,and thus lock said main shaftagainst rotation, the friction-disk 9'riding idly on its bearings; butwhen the spring-force of 13 is overcome by the operator depressingthekey 12, the said arm of the lever 11 liberates the arm 10, and thefriction-disk 9 operates to revolve the main shaft D one fullrevolution, or until the said 'arms again abut to lock the shaft Dagainst further movement.

E designates a stationary drum furnishing pivotal bearings at 14 for aseries of helleranklcvers, 15,in number corresponding to differentsymbols upon a series of type disks, which will presently be described,and with the keys upon the key-board. The keys 16 are provided withsymbols correspondin; to the symbols upon the type disks, and said keysmay be arranged in any convenient and approved manner, each keyconnecting with its appropriate bell-crank lever,17,'a'nd each lever 17connecting with its appropriate lever 15, and a spring, 18, serving witha constant force to hold its appropriatelever, 15, at a position of restuntil its force is overcome by the dcpression of the correspondingkey.For coir vcnience hereinafterthe levers 17 willbe designated askey-levers, and the levers as pinlevers.

F designates a stationary circular frame, to which is secured acylindrical frame composed of an outer cylinder, 19, and an inner cylinder, 20," the two being arranged at a distance apart and concentric toeach other. This frame is not an absolute cylinder, as at its lowestpoint it is reversed to form a recess, 21, in which is located aplaten-guide, 22, which will be described.

I provide a series of type-disks, G, which are loosely hung on the shaftD. Each type;

adapted to be received in its appropriate recess 24. Thus arranged, thetype will have lateral play due to the flexibility of the arms 25, butwill each be held securely in its relative position by the arms of thedisks 23, which arms form the recesses. The type-disks thus formed arehung loosely upon the shaft D, within the frame F, and between eachadjacent pair of disks I locate springfriction spiders 27, having radialspring-arms 28 and inwardly-projecting ribs 29, which engage inlongitudinal grooves 30, formed in the main shaft D. These spiders arehung upon the shaft D alternately with the typedisks, the arms 28 beingbent in alternately-opposite directions when thus arranged, theprojections 29 having formed engagements in the grooves 30, the spidersare forced to revolve with the shaft D, and the spring-arms 28-say sixin number-- bear three at equidistant points upon one type-disk, whilethe remaining three bear similarly upon the type-disk on the oppositeside.

The cylinder 19 is provided upon its outer surface with longitudinalridges 3t, and between the ridges 31 the said cylinder is perforated at32 to correspond radially with perfo rations made in the inner cylinder,20. A band, 33. of rubber or other elastic material, is stretched acrossthe ridges and arranged at one side of each circu m ferential row ofholes. Pins 34,whiclr-l will designateas stop-pins, operate through thecylinders 19 and 20, and each pin is provided with an arm, 35, which armis adapted to rest upon the outer surface of the band about midwaybetween the adjacent ridges 31. The perforations in the inner cylinder,20, are slightly larger than the pins,aud each pin 31 is provided with arecess, 36.- As the pin 34 isforced toward the center ofthe shaft D in aradial line the arm 35 bears upon the rubber band 33, and as this bandis stretched between two of the ridgesthe tendency is to tilt the pins34, so that their recesses 36 will receive the edges of the perforationsin the inner cylinder, 20, and lock the pins in that position. The pins34 also pass loosely through a trip-cylinder, H, and as this cylinder isforced in one direction by means yet to be described, all the pins whichhave locked in (see Figs. 3, 12, and 13) will be released, when theaction of the several bands 33 will promptly carry them back to theirnormal position.

I designates a movable ring, hung on rods 37, which slide in properguides in a direction parallel with the main shaft D, springs 38 servingto hold them with a constant force in the direction of the key-board, ortoward the front of the machine. Each of these rods 37 is provided, nearits end upon its lower surface, with arack, 39, which is engaged by asegmental gear, 7, one of which carries the disk 6, which is rigid withthe shaft 4, and one of them,in addition to the rack 39,has a rack, 40,provided on either edge, arranged so that a tooth upon either rack 40will be opposite the center of the space between two teeth of the rackupon the opposite side, and constructed so that the space between twoadjacent teeth on either rack 40 will be equal to the space between thecenter of one pin 34 and the center of the next adjacent pin.

A movable ring, 41, is arranged concentric to the shaft 1), and locatedso that the depression of any of the keys will bring the inner arm ofeither of the pin-levers, 15, against its inner surface and force ittoward the keyboard. This action will tilt a crank-lever, 42, upon itspivot 43, and by reason of its free end having a jaw, 44, which receivesa pin, 45, upon a double pawl, 46, the said pawl is dis engaged from theinner rack 40.

It will be understood thatthe constant lendency of the movable ring I,by reason of the springs 38, is toward the key-board, and that theaction of the frictional connection between the disks 5 and 6 is toovercome these springs and force the rings in the opposite direction, aswould be the case but for the action of the double pawl and itsconnections, as described. The spring 47 serves to hold the pawl 46engaged with the inner rack-bar40,and the ringI is locked. As soon as akey 16 is depressed, one of the levers 15 forces the ring 41 in adirection to tilt the lever 42, and said lever, acting on the doublepawl, disengages it from the inner rack 40, and the friction connection5 and 6 forces the ring I against the action of the springs 38 until theother jaw of the pawl engages the outer rack, when the ring I is againstopped. As soon as the pressure of the key is released, the spring 18forces the lever 15 out of contact with the ring 41, and the spring 47tilts the lever 43 back untilthe pawl 46 again engages the inner rack40. This ring I at each of its complete strokes, as just described,passes the distance between one of the stop-pins 34 and the nextadjacent stop-pin, and the said ring is provided with perforations andpins 48 to correspond with the number of pins 34, and the operation ofthis part of the machine will be briefly described as follows, referringto Figs. 2, 1, and 3: The operator, let it be supposed, wishes toarrange the types for a sentence commencing with K. He first depressesthe key 16,

havingasymbol corresponding to K, which action tilts the correspondingkey-lever, 17, through which the corresponding pin-lever, 15, is tilteduntil the horizontal arm thereof has forced the corresponding pin, 48,against the K stop-pin 34. This latter pin is forced inward against theinfluence of the band 33, (see Fig. 12,) and by the action of said bandis tilted until itislocked. (See Fig. 13.) Each type-disk is providedwith a stop, 49,,(sec Fig. 3,) and as soon as that stop 49 strikesagainst the K pin 34, thcletter K is in its position at the mouth of theplaten-box 22, as will be seen by running the alphabet back from thestop 49 in Fig. 3. The action of bringing that disk in the positionshown in Fig. 3, however, is not performed at this stage,

and I will continue the description with the K stop-pin locked. Theaction of the lever 15 has, through the lever 42 and pawl 46, releasedthe rod 37, and as soon as the stop-pin has been locked and the key hasreturned to its position, the lever-pin 48 has been forced quickly backto its normal position by the action of its spring 50; the frictionbetween the disks 5 and 6 has operated to force the ring I to the nextadjacent type disk, where it is locked by the pawl 46, as influenced bythe spring 47. The letter K now having been designated, and the partsall having returned to their normal positions, except that the ring I isadjusted over the succeeding annular row of stop-pins, the machine isready for as many similar subsequent operations as there are type-disks,or until as many stop-pins are locked inward, and as many lettersdesignated as are needed. It now being desirable to locate the severaldesignated letters in aline opposite the mouth of the platen-box 22, thekey 12 is depressed. This action, through the lever 11, releases the arm10 of the main shaft D, the friction-disk 9 operates to revolve theshaft D, and all the type-disks turn with said shaft until one afteranother the stops 49 on the several disks abut against the stop-pins, asseen in Fig. 3, and the several letters desig nated by such pins arebrought to one point, the frictionconnections 27 28 compelling all thedisks to turn with the shaft D until each is stopped by its abuttingagainst a stop-pin. As soon as the shaft D has made one full revolution,which is all that is required to bring all the disks into contact withthe stop-pins, the arm 10 again strikes the stop-lever l1, and thefriction-disk 9" acts idly on the shaft D, which again assumes aposition of rest. The friction-contact between the disks 5 and 6, as hasbeen stated, is sufficient to overcome the force of the springs 38, andas the ring I and its connections have made their complete, stroke Iprovide means for allowing said springs 38 to relieve the ring I inordcrthat it may operate similarly in relation to the stop-pins andtype-disks to designate other letters and combinations of letters. Tothis end, K designates a bellcrank lever pivoted to the side of theframe X at 51, and carrying upon its free end a grapple or fork, 52,which operates behind a collar, 53, to force the friction-disk5 out ofcontact with the disk 6. Upon the other end is formed an incline, 54,against which the arm 10 ot' the shaft D strikes when the shaft D isnear the end of its revolution. As this arm 10 rides up this incline 54,the lever K tilts or rocks on its pivot 51, and disengages thefriction-disk 5 from its bearing on the friction-wheel 6. To providethat no considerable friction shall retard the action of the springs 38,a trip-lever, 55, rests under a pin, 56, on the lever K until said leveris struck by a pin, 57, onthe rod 37 as the ring I passes backto itsnormal position, a spring, 58, forcing the lever .55 back for subsequentsimilar operation. As soon as the ringI and rods 87 are thus liberatedfrom the action of the friction-disks 5 and 6, the springs 38 reassertthemselves and throw said ring and its connections back to the positionshown in Fig. 2, at which point the said ring strikes the trip-cylinderH, and ashort stroke of said cylinder disengages each of the designatingstop-pins 34 from its locked position, and the rubber bands force themback into their normal position. Before the impression is taken it isnecessary that the types should be pressed close together compactly inline and held firmlyin such position.- To this end I employ a circularreciprocating head, L, to

which are connected twolongitudiual bars, 59,

the rear ends of which act against springs 60, located in sockets 6L inclamps 62, which embrace cams 63 upon the shaft B. Rigid with the shaftB is an arm, 61, which at one point of its revolution abuts squarelyagainst a pawl, 65, which is loosely hung on a rockshaft, M, journaledin standards 66, and carries an arm, 67. An arm, 68, upon the rear endof the main shaft D is arranged to strike this arm 67 just before itfinishes its revolutionthat is to say, after said shaft D has arrangedall the designated types in line-.and

. this action of the arm 68 releases the pawl from the arm 64, thusreleasing the shaft B. Between a collar, 69, on the shaft B and the endof the sleeve 1, on which the drive-pulley A is hung, is located aspringfriction-disk, 70, and this disk operates idly upon the collar 69 of theshaft B until the arm 64 has been liberated by the pawl 65, when, byreason of the friction, the shaft B revolves. As this revolution of theshaft B is being made, the cam action forces the rods 59 and head Lagainst the type-disks to bring them close together, and at the sametime a lever, 71, having a slot, 72, in which operates a pin, 73, of asocket, 74, forces a longitudinal bar, 75, the rear end of whichoperates against a spring, 76, so that its forward end, 77,will strikethe line of designated types, now located at the mouth of the platen-box22, and force them compactly together. It is also necessary that thedesignated types should now be held against lateral displacement, and tothis end each type is providcd' upon opposite sides with recesses 78.Secured at 79 to the socket 74 is a rod, 80, which passes approximatelyparallel with the bar 75, and is provided at its forward end with aframe, 81, having flanges 82, which slide in guides 83, formed in theplaten box near its mouth, and having also flanges 84, which slide inthe type-recesses 78. It will thus be observed that at the same time thehead L is forcing the type'disks together as a body the bar 75 isfurther forcing the particular types, which have been designated,together, and that the frame 81 has been simultaneously operated to holdthe designated types in alocked position. (See Fig. 11.) As thusconditioned the machineis ready for taking the impression. Forconvenience, I describe the impressionreceiving surface as of paper; butit is apparcut that the kind of material is not important to theinvention.

N designates a reel or roller carrying a tape, 85, which is adapted tobe fed through the machine beneath the type at the mouth of theplaten-box, and resting upon a platen, O,which operates loosely in thebox or well 22. Under a pin, 86, on the platen O, rests the end of apower-lever, 87, pivoted at 88 to the frame X, its free end passingrearward and resting in the line or track of the arm 64. In therevolution of this arm 61 it acts upon the lever 87, the pivot 88 ofwhich is arranged so as to multiply the power greatly to elevate theplaten O, which movement carries the paper-tape 85 up against the lineof designated types, now pressed and locked into a compact body, andtakes the impression. As soon as this is done, the arm 64 has passedfrom the lever 87, the cam 88 has changed position, the spring 89retracts the rod 75 77 and holding frame 81, and the platen 0 falls bygravity to its normal position by reason of the spring 100 acting tothrow upward the free end of lever 87, which correspondingly lowers theother end of the said lever where it engages the pin 86 of the platen.The tape 85 passes between feedrollers 90, one of which is provided witha ratchet, 91. with which engages a pawl, 92, pivoted at 93 to theframe, and held forward by a spring, 9L To the free end of the pawlarmis secured a cord, 95, which, passing rearward under a pulley, 96, andupward over a pulley, 97, is secured to the socket 74. As this socket 74is forced forward, as just described, to compress the types, the rope orcord 95 is slackened and the spring forces the pawl 92 idly over theratchet to take up said slack; but as soon as the impression has beentaken and the socket 74 is passing rearward, the cord forces the pawl92into engagement with the ratchet, and the paper is fed forward adistance just equal to the space occupied by the compressed type, theparts being properly proportioned to that end.

It will be observed that the several movements described are automatic,and it must be understood that the several parts are propor tioned andtimed to effect the operations men tioned.

The voluntary acts of the operator may properly be said to consist ofthe manipulation of the keys to designate the types, and, sec ond, thedepression of the key 12 to set the machine in motion. The stop-pinslock and unlock automatically. The designated types are brought to acommon point automatically. The types are compressed and locked automatically. The platen is operated automatic ally. The receiving-surfaceis fed to the type automatically, and the several parts return to theirnormal positions for similar subsequent operations automatically. Thesemovements are timed so that the first action of the machine is todesignate the types, the next to bring the designated types to theplaten-box in a line, and at the same time, or as soon as they are inline,'to compress them compactly and lock them, then to retract the ringI and release the stop-pins, then to take the impression, then to feedfor the next impression.

Modifications in details of construction may be made without departingfrom the principle or sacrificing the advantages of my invention, theessential features of which will be readily understood from theforegoing description, taken in connection with the drawingsas, forinstance, a positive gear or clutch may be employed instead of thefriction-disks 9 and 70, and weights may be used in several connectionsinstead of springs.
